Description

515709 A7 B7 V. Description of the invention (1) Background of the invention Field of the invention The present invention relates to a sheet that can transfer skin care oily ingredients to the skin of a user. More specifically, the present invention relates to sheets that can be used in absorbent articles, such as disposable diapers, sanitary napkins, pantiliners, incontinence pads, etc., and can be used to protect wound paper, skin care wipes, etc. Of thin slices. Description of Related Art Recently, various kinds of absorbent articles for absorbing feces have been used, for example, including disposable diapers, toilet paper towels, sanitary pads, and incontinence pads. When worn, the absorbent article is moistened by the wearer's sweat, urine, feces, menstruation, and other vaginal discharges, which usually gives the wearer a sweltering feeling and makes the wearer's skin allergic (eg, diaper rash class). In particular, the private parts and nearby areas that directly contact the excrement, and the elastic band parts that directly contact the absorbent products, such as near the waist and near the thighs, are more serious. A lotion or cream containing skin care ingredients is usually applied to the wearer's skin to prevent the wearer's skin from being impermeable or allergic to the wet absorbent article. However, this is still problematic, the lotion or cream can stain your hands and is a bit cumbersome to use. Especially babies and the elderly, they cannot apply their own skin and need the help of a caregiver, which is also troublesome. In order to solve the above problems, Japanese Unexamined Patent Publication (Kyhyo) No. 10 — 5 0 9895 and No. 10 — 509896 reveal that a paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the back first) (Please note this page before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs

Immovable agents that do not move the skin. However, the immovable agent will move at a certain temperature, even during storage or transportation of the diaper, and thus the necessary emollient will be lost before use. If so, the effective amount of this emollient will decrease during actual wear. On the other hand, sheets for protecting wounded areas such as wound-care adhesive tape (Band-Aic ^ i trademark) have been widely used, and they are directly used on the wounded areas of the skin. However, this type of sheet only protects the injured area from physical irritation without considering skin protection factors. Skin care flakes for the skin under normal conditions have been developed. To apply the oily ingredient to the skin to form an oily film immediately, it is preferably liquid or semi-solid. However, when the liquid or semi-solid oily component is applied to a sheet, the oily component may move before or at the time when the sheet contacts the skin, and an oily film cannot be formed at the intended skin site.

Description of the invention (6) Description of preferred specific examples One of the specific examples of the present invention is a disposable diaper, which is an absorbent article, which is described in the accompanying drawings. This specific example is a sheet having the oily component layer of the present invention. Fig. 1 is a plan view of the diaper with a liquid-absorbing edge at the front end. In this example, the top sheet of the diaper is made of a sheet having an oily component layer according to the present invention. Fig. 2 is a cross-sectional view of Fig. 1 cut along the line I I-I I. As shown in FIG. 1, the disposable diaper 1 of the present invention is an hourglass-shaped, open-type diaper. The disposable diaper is composed of a front end region 2 A to be placed on the abdomen of the wearer, a rear end region 2 C to be placed on the buttocks and / or behind, and a central region 2 B to be placed on the crotch. In this example, the direction extending from the front region through the central region to the rear region is designated Y (this is the longitudinal direction of the diaper); and the direction perpendicular to Y is designated X (this is the transverse direction of the diaper). As shown in FIG. 2, the direction extending toward the wearer is designated as Z. The disposable diaper 1 includes a liquid that is in contact with the wearer's skin and penetrates the top sheet 10, a liquid that is in contact with an external support (such as underwear) is a non-penetrable bottom sheet 1 1 (as opposed to the top sheet 10), and a sandwich Absorbent cores 12 on top sheet 10 and bottom sheet 1 1. All of the top sheet 10, the bottom sheet 11 and the absorbent core 12 have an hourglass shape. In the periphery of the absorption core 12, the top sheet 10 and the bottom sheet 11 are adhered to each other by a hot-melt adhesive or the like. When the diaper 1 is worn, the rear hem protruding from the rear end region 2 C is respectively disposed on the bottom panel 1 1 ′ of the front end region 2 A and the interlocking panel 1 8 (located at the rear hem of the rear end region 2 C). The paper size of the top sheet 10 in the middle of this paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ^ (Please read the precautions on the back before filling this page) Threading-Consumption by the Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumer Cooperative, 515709 A7 B7 V. Description of the invention (7) The edge is the interlocking area 1 7 (located in the waist of the wearer, before the front area 2 A protrudes in the direction X) The bottom pieces 1 1) of the folded edges are interlocked. When the diaper 1 is thus worn, the elastic member 16 stretches and contracts elastically around the waist of the wearer, and makes the diaper 1 and the waist of the wearer's body fit tightly. The diaper 1 of the present invention is provided with a liquid-absorbent strip-shaped sheet 30 near the longitudinal side edge 4 of the top sheet 1; and the other edge of each strip-shaped sheet 30 connected to the center of the diaper 1 (such as The unfixed end of the strip piece 30) has an elastic element 31. The other side edge of each strip sheet 30 and the remaining two opposite side edges are connected to the uppermost surface of the top sheet 10 to form a pair of leak-proof folds 32. When the diaper 1 is worn, the unfixed end of each hem 32 connected to the center of the diaper 1 will stand to prevent side leakage, and the upper layer of each leak-proof hem 32 in the direction Z will contact the wearer's skin. Keep in touch. In the range of the two side edges 4, the side edges 4 are along the direction X of the diaper 1 (eg, the longitudinal side edges), and the absorption core 12 does not exist (this is outside the absorption range of the diaper 1), The elastic element 35 is connected to and fixed to the diaper 1 between the top sheet 10 and the bottom sheet 11, and extends in the direction Y of the diaper 1. The elastic element 35 elastically stretches and contracts in the direction Y, and the top sheet 10 and the bottom sheet 11 thereof elastically stretch and contract in the direction X of the diaper at the two side edges 4. When the diaper 1 is being worn, the elastic element 35 thus forms a pair of leg hem that remains in contact with the thigh of the wearer.

515709 A7 B7 5. Description of the invention (8) A mixture layer 50 (containing at least the following two ingredients (a), (b)) is used for the surface of the top sheet 10 (this surface is also referred to as the body contact surface) The top sheet is used to absorb excrement discharged by the wearer. (a) an oily ingredient that is liquid or semi-solid at 25 ° C; and (b) an ester compound of dextrin and fatty acid. The oily ingredient (a) is a compound that forms an oily film on the top layer of the wearer's skin to protect the wearer's skin from allergies. An oily film formed on the wearer's skin protects the skin from chemical irritation caused by fecal matter and surfactants and from physical irritation caused by diaper-to-skin contact. More preferably, the oily component (a) is insoluble in water, so that the oily film thus formed will not dissolve on the skin, and will not be lost to the wearer's sweat and feces. However, it may be a compound that is emulsified in water (when mixed and shaken with water) through the use of emulsifiers. Even better, it can be a fatty acid having a hydrophilic group as an oily component. In the case of using a fatty acid, even if the oily component has a hydrophilic group and widely spreads on the surface of the top sheet 10, the liquid permeability of the top sheet 10 is hardly reduced. Since the oily film-forming compound is intended to directly contact the wearer's skin, it is preferred that the compound is colorless or white, or at least nearly colorless or nearly white. Specific examples of the oily component (a) are described below, but they are not limited thereto. Needless to say, any other compound not mentioned below can also be used in the present invention as long as it has the ability to form an oily film. One or more of the following (please read the notes on the back before filling this page)

Description of the invention (10) (6) Hydrocarbons hydrocarbons with 14 or 15 carbon atoms, vaseline, stone stone, squalene, pristane, ground Oz (ozocerite, ceresine), microcrystalline 鱲 ... and so on. (7) Derivatives of the oily ingredients (1) to (6), the unsaturated portion derived from the compound is hydrogenated. Among the above oily ingredients, those commonly used in cosmetics are preferred because they do not cause skin irritation. More preferred is a dialkyl carbonate having 14 or 15 carbon atoms, because it is non-hazardous and can be spread on the skin sufficiently. It is also better to use a vegetable oil, such as macadamia oil, mixed with a dialkyl carbonate having 14 or 15 carbon atoms, which is non-irritating to the skin. In view of its gelation ability, which will be described in detail later, the oily component compound preferably has a polar group. However, the gelation ability of this oily ingredient can be controlled by changing its viscosity, or an oily ingredient can be prepared by mixing multiple compounds. Compounds without polar groups can also be used as oily ingredients. The oily component (a) is liquid or semi-solid at room temperature, because it must be applied to the skin. Therefore, if only the oily ingredient is used in the diaper 1, it will penetrate into the constituent elements of the diaper 1, or pass through before or at the time when the diaper 1 is actually worn. Thus, the necessary amount of the oily component cannot be transferred to the skin of the wearer. Therefore, an ester compound (b) of dextrin and fatty acid is added to the oily component (a), so that the oily component (a) and the ester compound (b) are gelatinized and fixed on the surface of the top sheet 10 of the diaper 1. -(Please read the precautions on the back before filling out this page) Order the paper printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs to apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 515709 Intellectual Property Bureau of the Ministry of Economic Affairs Printed by employee consumer cooperative A7 __ B7 Five 'invention description (i) When the oily component (a) is mixed with the ester compound (b), the resulting mixture will form a colloid. When the colloidal mixture is applied to the surface of the top sheet 10, the high possibility of penetration from the top sheet 10 to the absorbent core 12 is prevented. Therefore, the layer 50 can be reliably formed on the surface of the top sheet 10. When the diaper 1 is worn, the mixture layer 50 formed on the top sheet 10 will contact the wearer's skin, and therefore, the oily component (a) in the gelled layer 50 will melt and move toward the skin, thereby causing skin An oily film was formed on it. At room temperature, the gelled mixture layer 50 is not easy to move, and it will surely form an oily film in a predetermined area only when it is in contact with the skin. In the ester compound (b), dextrin forms an ester bond with a fatty acid. Herein, the fatty acid has a large number of carbon atoms to produce a mixture of (a) and (b) having a higher gelling power. Therefore, it is desirable in the present invention that the fatty acid has 12 to 22 carbon atoms. If the number of carbon atoms of the constituent fatty acid is less than the minimum of the above range, the gelation power of the mixture is poor. In this case, the layer 50 of the mixture will penetrate from the top sheet 10 to the absorbent core 12 and therefore, the absorbency of the absorbent core 12 of the diaper 1 will be reduced 'and the necessary amount of the oily component cannot be transferred to the wearer's skin. On the other hand, if the number of carbon atoms of the constituent fatty acid exceeds the maximum limit of the above range, the gelation force of the mixture will be too high. In this way, the oily component can hardly be transferred to the skin, so that the mixture layer 50 cannot bring a comfortable feeling to the wearer. Fatty acids with many carbon atoms have higher melting points. Therefore, 'If the number of carbon atoms of the fatty acid used in the present invention exceeds the upper limit of the above range', the mixture must be heated at a high temperature when the layer 50 is formed. And-(Please read the precautions on the back before filling this page) Order The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 515709 A7 B7 V. Description of the invention (12) The ester compound in the mixture will be changed to its essence by the above-mentioned high temperature. In addition, when the mixture layer 50 heated at a high temperature is formed on the top sheet 10, the touch of the top sheet 10 is deteriorated. Preferable examples of the ester compound are dextrin palmitate, dextrin stearate, dextrin camelliate, dextrin myristate, cocoa dextrin, dextrin laurate, and others. Esters of fatty acids of 2 to 2 carbon atoms. Among these, a non-dangerous person who can be used for cosmetics is preferable. Even better is dextrin palmitate, which is both colorless and non-hazardous. By the mixture of (a) and (b), the oily component (a) accounts for 30% to 98% by weight, and the ester compound (b) accounts for 70% to 2% by weight (ie, the oily component (a)) The ratio of the ester compound (b) is between 30:70 and 98: 2), so that the oily component (a) can form an oily film on the skin of the wearer, and gelate well to fix it On the diaper 1. More preferably, the oily component (a) accounts for 70% to 95% by weight, and the ester compound (b) accounts for 30% to 5% by weight (that is, the oily component (a) accounts for the ester compound (b). ) Is a ratio between 7 0: 3 0 and 9 5 ·· 5). In the mixture layer 50, the dextrin and fatty acid ester compound (b) exists in a gel network structure. Before the disposable diaper 1 is used, the oily component (a) is liquid or semi-solid and is contained in the gel network structure. In other words, the ester compound (b) having a gel network structure is in an expanded (sw ο 11 e η) state by the oil ions (a). When the disposable diaper 1 is placed on the wearer, and the mixture layer 50 applied to the top sheet 10 will contact the wearer's skin, an external force such as exhaustion is applied, and the scale is applicable to the Chinese National Standard (CNS) Α4 specification ( 210X297 mm) '15 (Please read the notes on the back before filling this page) Printed by the Employees ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed 515709 A7 ____ B7 V. Description of the invention (13) Physical pressure and friction will act on The mixture layer 50. Due to this external force, the gel network structure of the ester compound (b) will be destroyed, and the oily component (a) therein will be released to be transferred to the skin of the wearer. In the present invention, since the oily component (a) is bound to the gel network structure by the ester compound (b), the amount of the oily component (a) transferred to the absorption core 12 may be greatly reduced. On the other hand, during manufacture, transportation, or storage, it is possible to reliably prevent oily components from being lost before use. Furthermore, the present invention has a mechanism such that the gel network structure of the ester compound (b) is destroyed by external force, and the oily component (a) is released to be transferred to the skin of the wearer. Therefore, the oily component of the mixture layer 5 can be effectively transferred to the wearer's skin. Furthermore, even after the gel network structure is damaged, the ester compound (b) remains on the top sheet 10, and only the oily component (a) is transferred to the skin of the wearer. In other words, because only the oily component (a) can be selectively transferred to the wearer's skin, the amount of the oily component (a) required to give a predetermined protection benefit can be reduced. In the above-mentioned preferred examples of the ester compound, dextrin palmitate has superior storage efficiency (a) of the oily component (a). Furthermore, when dextrin palmitate is used as the ester compound (b), dextrin palmitate will produce fine crystals on the top sheet 10 to improve the lubricity and feel. Fig. 7 is a structural formula of a dextrin palmitate according to an embodiment of the ester compound of the present invention. As shown in Figure 7, dextrin palmitate is contained in polysaccharides, and its glucosides-(Please read the precautions on the back before filling this page), 1T Printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economic Affairs Paper size Applicable to China National Standard (CNS) A4 Specification (210 × 297 mm) 515709 Α7 B7 V. Description of Invention (14) (Please read the notes on the back before filling this page) The combination is effective. That is, the hydroxyl group of glucose 1 1 0 is palmitized and is bound together by α 1 -4 glucoside binding or α 1 -6 glucoside binding. In FIG. 7, the fluorenyl groups at the 2 position and the 3 position are represented by COR and COR and CO (CH2) 14CH3, respectively. As shown in Figure 7, dextrin palmitate has a polysaccharide chain structure, which is aggregated into a network structure through hydrogen bonds between polysaccharide chains, or a hydrophobic structure forms a gel structure. Oily ingredients (a) such as dialkyl carbonate 1 1 1 are retained in the gel structure due to the hydrophobic interaction with the phosphonium group of dextrin palmitate. Since the mixture of (a) and (b) is Used to directly contact the wearer 'it must not cause skin irritation. For example, human skin under normal conditions usually has a pH 値 of 4.5 to 7.5. Thus, a mixture layer having 4 · 5 to 7 · 5 P Η 値 is satisfactory, and more preferably 5 · ◦ to 7 · 0. In addition, because the mixture clings to the wearer's skin, it is desirable that the mixture is colorless or white, or nearly colorless or nearly white. The mixture of (a) and (b) printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs may further contain any skin care ingredient. For example, it may contain any anti-inflammatory ingredients such as Gou Yao, Scutellaria root, Samt-John grass, chamomile, peach leaf, loquat leaf, mugwort, perilla extract, etc .; body creams such as fibroin, sericin, collagen , Seaweed extracts, etc .; antioxidant (deodorant) ingredients such as green tea, bamboo extracts, etc .; p Η regulators (or such as those that maintain the wearer's skin slightly acidic), such as natural fruit acids (malic, succinic, Citric acid, tartaric acid, lactic acid, etc.), this paper size applies Chinese National Standard (CNS) A4 specification (210 x 297 mm) 515709 A7 _ B7 __ V. Description of the invention (15) Alkali metal salt and alkaline earth metal salt (phosphate , Carbonates, etc.) and so on. Depending on the condition of the wearer's skin, this additional skincare ingredient can be formulated or added to the mixture in any way. The mixture may contain a surfactant to allow oily ingredients to penetrate the skin. As the surfactant, it is preferable to have a fatty acid sucrose ester which does not cause skin sensitization. The mixture layer 50 may be formed by applying a predetermined amount of the mixture to the top sheet 10 (matrix). For example, the mixture can be applied by printing, such as gravure or flexographic letterpress. Coating technology using thermal adhesives (such as hot melt adhesives) can also be used. Specifically, the mixture forming this layer is melted using a hot-melt coater, and then (1) a predetermined amount of the obtained melt is extruded through a gear drum, and by using a slot coater and The mold in contact with the substrate is directly coated on the substrate; or (2) the melt is extruded through the mold and then applied to the substrate under air pressure; or (3) the melt is transmitted through The mold is extruded like a fiber and is directly attached to the substrate. What is used here is still a dyeing technique. Specifically, the substrate is directly impregnated with the coating solution of the mixture forming the layer, and the excess coating solution is then unscrewed (this is referred to as dip). In order to ensure that the minimum coating amount of the mixture is used to form the maximum coating effect of the desired layer, it is preferred that the mixture is the main fibrous area applied to the substrate. For this effect, among the aforementioned techniques, it is considered that this printing technique (gravure printing or elastic letterpress printing) and the application technique of a thermal adhesive are better. Regarding the coating pattern of layer 50, the entire surface of the substrate can be uniformly coated with the layer, as shown in FIG. 2. It is also possible to make the layer have a stripe pattern as shown in Figure 3 A.

On the other hand, a non-woven fabric may be used as the bottom sheet 1 1, and a waterproof sheet sandwiched between the bottom sheet and the absorbent core. When it is placed on another absorbent article, the back sheet 11 can be made of a liquid-permeable sheet material. The absorbent core 12 may be formed of an absorbent material, for example, powdered pulp or a mixture thereof with a superabsorbent polymer. In this connection, powdery pulp or a mixture thereof with a superabsorbent polymer can be wrapped by an absorbent sheet such as tissue paper. For example, the interlocking area 17 may be an adhesive tape of rubber or acrylic resin, etc .; and the interlocking sheet 18 may be made of a resin sheet. In the specific example shown in the figure, the mixture layer 50 is present in the entire range of the absorption core 12, but may not be in the entire range. For example, 50 can be placed on the front end area 2 a of the wearer's abdominal zone, and / or the bottom area of the wearer's buttocks and / or the bottom rear area 2 C, to prevent the wearer's abdominal area and buttocks from allergies, and Reduce the liquid permeability of the top sheet 10. Not limited to this, the layer 50 can be used in other parts of the diaper 1, which will fit the Chinese standard (CNS) A4 specification (210X 297 mm) with the size of this paper; 20-(Please read the precautions on the back before (Fill in this page)

Description of the invention (18) The skin is in direct contact with the person. Fig. 4 is a partial cross-section of a second specific example of the present invention, and corresponds to Fig. 2 showing the first specific example described above. In the specific example of FIG. 4, the unfixed end portion of each leak-proof hem 32 (which will directly contact the wearer's skin with the elastic element 3 1) is coated with a mixture layer 50. Furthermore, the region adjacent to the side edge 4 forms a leg hem (which will directly contact the wearer's thigh and has an elastic element 3 5) coated with a mixture layer 50. In this specific example, this layer 50 protects the skin of the wearer's crotch and thighs from allergies. When the wearer wears the diaper, the skin contacting the elastic member of the diaper is susceptible to a lot of physical irritation 'because it is often rubbed by the elastic member. Therefore, it is desirable that the skin of the wearer in this area can be protected in particular in the manner illustrated by the present invention. In addition to the specific examples described here, the mixture layer 50 can be used as a waist portion of a diaper having an elastic member 16. Examples of the absorbent article having the sheet of the present invention include the first and second specific examples of the open type diaper described above. Without being limited thereto, the present invention can be applied to any other articles such as pant-type diapers, incontinence pads, toilet paper towels, sanitary pads, and the like. Fig. 5 is a plan view of a third specific example of the present invention, in which the sheet of the present invention has an oil-containing component layer for protecting an injured part. Fig. 6 is a cross-sectional view of Fig. 5 cut along the line VI-VI. As shown in Fig. 5, the sheet 100 for protecting the injured part is used to cover the injured part of the skin to avoid contact with other objects.

Description of the invention (19) A substrate sheet such as a fabric 1 0 1. Gauze 1 0 located on the middle of the substrate sheet 1 0 2. Surrounded by The gauze 10 02 is composed of (a) (b) a mixture layer 50, and an adhesive layer 103 located on each side edge portion of the substrate sheet 101. In its application, the sheet 100 for protecting the injured part directly acts on the skin, so that the gauze 102 will directly contact the injured part of the skin, and it is in close contact with the skin through the adhesive layer 103. Because the sheet 100, which protects the injured part, contains a mixture layer 50, when it adheres to the skin, an oily film is formed near the injured part of the skin. This oily film protects the skin near the injured area so as to reduce the range of skin caused by the adhesive layer 103. In the sheet 100, the gelling mixture layer 50 does not move to other areas of the substrate sheet 101 and does not penetrate into the substrate sheet 101, so it is hardly wasted. In this specific example, the mixture layer 50 may also be formed on the surface of the gauze 102 or only on the surface of the gauze 102. This specific example shows separately that the sheet of the present invention has an oily component layer therein, and can also be used as a skin care diaper under normal skin conditions. In such skin care diapers, the oily ingredient does not move out of the range of the base sheet before use. When in use, even if the diaper is kept in contact with the wearer, the oily components therein do not flow downward, and the mixture layer 50 can surely maintain contact with the skin-contacting surface. Under this condition, the oily ingredient is formed on the skin. 0 By using a sheet having an oily ingredient layer 'is undoubtedly a simplified method for applying the skincare oily ingredient to the skin. The oily component layer hardly moves on the sheet, and hardly penetrates into the substrate sheet, so a few --- (Please read the precautions on the back before filling this page) Alignment This paper size applies Chinese national standards (CNS) A4 specification (210 × 297 mm) 515709 A7 B7 V.
